Frequently Asked Questions

It is a type of grating that disperses, collimates, and refocuses light from the entrance slit onto the exit slit, with wavelength scanning obtained through a simple rotation of the grating. The groove spacing of these gratings is optimized to produce high-quality images with a minimum of astigmatism and coma.

We need the spectral range, configuration of use (monochromator or spectrograph), numeral aperture (F number) or size of grating, maximum overall dimension or maximum focal length, desired dispersion, desired resolution, entrance slit width and height or source geometry, and minimum deviation.

Type IV aberration-corrected monochromator gratings provide much better light collection efficiency and signal-to-noise ratio compared to Czerny-Turner monochromators, which are equipped with one plane grating, one collimating mirror, and one focusing mirror.
